Donovan, S.K., Jones, B., Harper, D.A.T.
The first fossil echinoids are recorded from the Cayman Islands. A regular echinoid, Arbacia? sp., the spatangoids Brissus sp. cf. B. oblongus Wright and Schizaster sp. cf. S. americanus (Clark), and the clypeasteroid Clypeaster sp. are from the Middle Miocene Cayman Formation. Test fragments of...

In 2009, New Zealand’s (NZ) new National-led government abandoned the Carbon Neutral Public Service (CNPS) program, a Labour-led government initiative intended to help Government achieve carbon neutrality within its core agencies. This short analysis article provides an overview and brief...

Nitrogen isotope fractionations among gaseous and aqueous NH4+, NH3, N2, and metal-ammine complexes: Theoretical calculations and applications
Download2021-02-15
Li, Long, He, Yuyang, Zhang, Zhe, Liu, Yun
Ammonium (NH4+), ammonia (NH3) and N2 are key nitrogen species in geological nitrogen recycling. NH3 has also been proposed to play an important role in mobilizing base metals in the form of metal-ammine complexes in hydrothermal fluids. The nitrogen isotope fractionation factors among these...

On the importance of the choice of wind stress forcing to the modeling of the Mediterranean Sea circulation
Download1998
Myers, Paul G., Josey, Simon, Haines, Keith
A 1/4° degree ocean general circulation model is used to examine the role that four different wind stress climatologies play on the circulation of the Mediterranean. The wind stress climatologies examined are those derived from numerical weather prediction models (National Meteorological Center...

Ongoing, long-term evolution of an unconformity that originated as a karstic surface in the Late Miocene: A case study from the Cayman Islands, British West Indies.
Download2015-01-01
On Grand Cayman and Cayman Brac, karst development on the upper surface of the Cayman Formation during the late Miocene lowstand produced the Cayman Unconformity. On Grand Cayman, this led to the development of a deep, atoll-shaped depression on the western part of the island. The ensuing Lower...

Overturning in the subpolar North Atlantic program: A new international ocean observing system
Download2017
Zika, J. , Inall, M., Pillar, H., Zhao, J., Li, F., Lozier, M., Bower, A., Houpert, L., Yang, J., Bacon, S., Greenan, B., Holliday, N., Thierry, V., Marshall, D., Heimbach, P., Weller, R., Pickart, R., Lin, X., Cunningham, S., Karstensen, J., Wilson, C., Johnson, H., deYoung, B., Gary, S., Williams, R., Straneo, F., Mackay, N., Johns, W., Fischer, J., Mercier, H., de Jong, M., de Steur, L., Myers, P.
For decades oceanographers have understood the Atlantic meridional overturning circulation (AMOC) to be primarily driven by changes in the production of deep-water formation in the subpolar and subarctic North Atlantic. Indeed, current Intergovernmental Panel on Climate Change (IPCC) projections...

Paleozoic reactivation structures in the Appalachian-Ouachita-Marathon foreland: Far-field deformation across Pangea
Download2017-04-03
Porter, Ryan, Malone, David H., Day, James E., Craddock, John P., Luczaj, John, Konstantinou, Alex, Johnston, Stephen T., Compton, John
The Proterozoic Grenville orogeny (~ 1300–980 Ma) reactivated the Archean-hosted Kapuskasing suture in Laurentia which then propagated west and south initiating the Keweenaw rift (1141–1085 Ma) which closed by thrust shortening at 1060 Ma. Late Proterozoic-Paleozoic sediments were then deformed...

Petrographic and geochemical features of sinkhole-filling deposits associated with an erosional unconformity on Grand Cayman.
Download2015-01-01
On Grand Cayman, exposures of dolostones belonging to the Cayman Formation (Miocene) represent an erosional unconformity that has been developing since the late Pliocene (~ 3.6 Ma). Sinkholes that developed during this time have remained open or become partly to fully filled with various...

Potential positive feedback between Greenland ice sheet melt and Baffin Bay heat content on the west Greenland shelf
Download2015
Hu, Xianmin, Myers, Paul G., de la Guardia, Laura C.
Greenland ice sheet meltwater runoff has been increasing in recent decades, especially in the southwest and the northeast. To determine the impact of this accelerating meltwater flux on Baffin Bay, we examine eight numerical experiments using an ocean-sea ice model: Nucleus for European Modelling...
